Heredity – Final Test Study Guide
Be able to identify, define, and use the following terms, giving examples where appropriate.
gene
heredity
genotype
purebred
heterozygous
incomplete dominance
recessive genetic disorders
chromosome
genetics
phenotype
homozygous
dominant
multiple alleles
sex-linked disorders
allele
Punnett square
hybrid
recessive
polygenic inheritance
chromosomal disorders
You should also be familiar with the work of Gregor Mendel:
 What was his nationality, profession and educational background?
 What did he do? What type of plant did he work with? Why?
 When did he do his work?
You should be able to clearly differentiate between an organism’s genotype and phenotype using examples to explain the
difference.
You should be able to correctly determine an organism’s genotype when given information about a trait, what its
dominant and recessive forms are, and the organism’s phenotype.
You should be able to make a Punnett square to show the crossing of parents alleles for a given trait. From this you
should be able to predict the potential phenotypes and their probability of occurrence.
